I have not been able to connect to internet through my hostel wifi in Linux(EEEbuntu 2.0 on my EEEPC 1000H. drivers are provided in distro itself), although it connects in windows. The system here is that we have to register our computer's mac addresses afterwhich we can simply connect to the wifi router and browse internet after filling in a proxy and port in the internet options. I have no Idea why they have to do that.

Here is the output of "ipconfig /all" that I did on windows

Code:

he mentioned something about filling in a proxy/port... and needs to elaborate on "i have not been able to connect"...

does the wifi card not work at all in linux? can you not get a signal to connect to?

can you try to enter that proxy information into firefox? i dont recall exactly where you would put in proxy info...
 
The drivers are already installed. I get signals too and it even connects to the router all right. But it still doesn't work. I must be putting in some values incorrectly.
I will put in the values of "ifconfig -a' after I finish the current download so that you can analyze the problem a little better.
Thanks in advance.

OK your windows wireless card hardware address is showing as "00-22-43-26-18-D9" but in Linux the "ra0" wireless hardware address is "00:22:43:26:18:cb".

So either try to also register this second address with your network if allowed or search online for setting hardware address in Linux network interface. You can do it with the ifconfig command I believe or perhaps module parameters. Google is your friend... :D

Who has setup the connection in the college hostel? I suppose it is the college hostel management itself. It's not the students or you, right :S

The proxy and port means that any data transfer has to go through that IP and port. So in the end , it means that they will be able to monitor the traffic and restrict the websites if they need. They will be having logs for each and every site you visit.. So be careful when you take thoooosee sites!!! :P

That's not a problem because none of them are my mac address. I have put it in just like that.
@methew: Actually they do monitor each and every site that we try to visit. Infact there are very few sites that we can actually visit. Can't download any media file..
So how do you suggest I can connect my linux box to this setup?
 
So? Anyone has a solution to this? Is there any chance that they have somehow restricted people with Linux systems? I am asking that because I can't connect even on the wired college network inspite of the fact that I have tried to replicate all the settings of the windows. I can even ping the default gateway pretty well but still unable to go online.
 
So no one has a solution to this? In gaming section I usually get a reply within 15 minutes :S

I understand that Networking, especially in Linux is a tricky subject and very few understand it fully. So do you suggest anything to get around this problem? Atleast tell about some forum with more hard core linux networking guys( Absolutely no offence meant. I love all my fellow techenclavians, but have to sort out this problem soon :D )

You know if I can get wifi working on my laptop and also connect linux to internet on the LAN network of my department, I will convert soooo many people to Linux. There are 15 computers in my computer lab, all with pirated windows and infected by viruses. The computer administer has told me so many times to install Linux on them if I can get the Internet to work on them.
 
Would surely have helped you but haven't used wifi till date :( So I have no idea about it :ashamed: Try ubuntuforums.org for much better and accurate help :)

@Darkstar: No problem. You are among the most knowledgeable and helpful linux gurus I know. You can't know everything all by yourself. That's why someone invented tech forums :D
Heading to the Ubuntu forums now.
 
I will try the proxy thing too. I think that may be something preventing me from connecting to the internet atleast on the wired network in my university.
